The five latest Bose NFC Bluetooth headsets (as of January, 2019)

The SoundSport Pulse, as its name suggests, sells its built-in heart rate monitor to the athletics-loving crowd -- all while also offering specs like an unimpressive 5-hour working time, NFC support, and Bluetooth version 4.2 (which is still uncommon among mid-2017 Bluetooth headsets).

A lightweight at 0.8 ounces, this sports NFC Bluetooth headset features specs like its six hours of music playback time in a two-hour charge, three different sizes of StayHear+ ear tips, and an in-line mic to remote design.

Rather lightweight (at 8.3 ounces compared to other headphones), this NFC Bluetooth headset banks on specs like a 20-hour music playback time that can be extended by 2.5 hours with a 15-minute charge, and a battery life of 40 hours on a wired mode

Despite having specs that may seem more of an inconvenience, such as its three hours of charging time, this around-the-neck Bluetooth headset, weighing only 2.3 ounces, is equipped with a manual noise cancellation system that complements its 10 hours of playback time. It is also capable of Music Share which allows two different users to listen to the same audio file simultaneously.

Heading this Bluetooth headset's specs list are a 15-hour playback time, a fast-charge feature (15 minutes of charging for two hours of playback), and the Bose Connect feature, which apparently aids in establishing connections.

And other models...

This cord-free in-ear Bluetooth headset features specs like IPX4 coating, a volume-optimized equalizer, and five hours of music playback time on a two-hour charge, which can be extended using its charging case yielding another ten hours of battery (a quick 15-minute charge can produce 45 minutes of usage).

Music-oriented headset that promises the deepest lows and the clearest highs but does not seem to even mention speaker diameter or frequency range metrics -- it also allows plugged usage for up to 20 hours of usage.
